• Combination of aspirin with VKA in patients with a mechanical prosthesis
• Optimal timing, doses, and type of heparin to be used early after
mechanical valve replacement
• Use of aspirin vs. VKA during the first three post-operative months following
aortic valve replacement using a bioprosthesis
• Use of DOACs in patients with a bioprosthesis
• Anti-thrombotic therapy after TAVI in patients in sinus rhythm and in AF
